how to organize an innovation event?

First of all, I got great receipt from managers, almost all of them will come, but not so good from employees, because they are at business trips or they have private reasons. But I expect that 50% will come surely, so the event will survive… What’s the main reason fo this event?First, I want to reward best innovators in last year, and to ‘make them important’. Second, to present the best ideas for all colleagues, but also for the managers on event, but also through the special brochure and intranet site to everybody in the company. This ideas should inspire future innovators, to see that the guy who sits in next room had a great idea, so why can’t he have one too?It took a lot of time for preparation, specially to make 35-page brochure with all participants and their ideas, but I think it’s worth, because each year, more and more ideas are submitted.Also, everyone is aking me about the event, and when will be this year’s. It’s also a good oportunity to introduce the new posters and awards for new season of innovation program.
